I am just starting with node.js. I have done a little ajax stuff but nothing too complicated so callbacks are still kind of over my head. I looked at async, but all I need is to run a few functions sequentially.
I basically have something that pulls some JSON from an API, creates a new one and then does something with that. Obviously, I can't just run it because it runs everything at once and has an empty JSON. Mostly the processes have to run sequentially, but if while pulling JSON from the API it can pull other JSON while it's waiting then that is fine. I just got confused when putting the callback in a loop. What do I do with the index? I think I have seen some places that use callbacks inside the loop as kind of a recursive function and don't use for loops at all.
Simple examples would help a lot.
